Specification of Letters l atent. Application filed Febrnary 15, 1911. Serial No. 608,675.

K! To all whom it may concern:

Be it known that I, OLOF A. CARLSSON, a citizen of the United States, residin at Chicago, in the county of Cook and tate of IlllIlQlS, have invented a new and useful Stopper, of which the following is a speci-.

fication.

It is the object of this invent on toprovide a stopper having a resilient flange 10.which may be compressed readily intotubular form, for insertion into.an opening in a receptacle, the flange expanding within the receptacle, to hold the stopper n place,

the construction being such that the stopper may be used repeatedly.

Another object of the invention is to provide a stopper which'may be inserted into and removed from a receptacle repeatedly, without injuring the stopper through outting contact with the receptacle, during the insertion and removal of the stopper.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter de-' scribed and claimed, it-being understood that changes in the precise .embodiment of invention herein disclosed can be made within the scope of what is claimed without departing from the'spirit of the invention.

In the drawings,-Figure 1 shows a modified form of the invention in transverse section mounted in a receptacle; Fig. 2 shows another modified form of the invention in transverse section, mounted in a receptacle of slightly different form from that shown in Fig. 1; Fig. 3 is a transverse section showing a still further modification, the receptacle with which the device is assembled, differing in form from those receptacles appearing in Figs. 1 and 2; Fig. 4' is a side elevation of a form of stopper; Fig. 5 is a side ,elevation showing the stopper; Fig. 6 is a side elevation showing the stopper of Fig. 1

with its flange portion compressed for insertion intothe receptacle; Fig. 7 is a sectional bottom plan of the stopper shown in Fig. 1; and Fig. 8 is a bottom plan of the stopper shown in Fig. 5.

The stogper shown in Fig. 1 comprises a body 1 an a flange '2, the stopper bein diminished in diameter between the body 1 and the flange 2,. to form a neck 3, adapted to be inserted into the top of a receptacle 4, which may be of any form. The invention, as de icted in Fig. 1, is a one 'ieee structure, t e same being preferably ash.- ioned from rubber. The flange 2, compared with the body 1, is relatively thin, the body 1 bein relatively ri id. The flange 2 1s foldab e away from t e body 1, into a'tubular form, as denoted by the numeral. 5 in Fig. 6, the diameter of which tubular portion is no greater than "the diameter of the neck 3, the construction, therefore, being such that the flange 2, when compressed into tubular form as shown at 5, may readily be inserted in the opening in. the top of the receptacle, without causin the rece tacle to cut into the stopper. hen the. ange 2, having been first compressedinto the tubular form denoted by the numeral 5, is inserted within the contour of thereceptacle 4, the flange will expand, as shown in Fig. 1, holding the stopper firmly in' place. Owing, however, to the thin, resilient character of the flange 2, the stopper mayreadily be withdrawn from the receptacle.

In the form of the invention shown in Fig. 2, the body 6 is much thicker than the flange 7, theneck 8 fitting as before, into an opening in the bottom of the receptacle 9,

the same, in the present instance, being shown in the form of a powder shaker. In

the form ofthe invention shown'in Fi 2, the body 6, compared with the flange is relatively rigid,'the device bein as in Fig. 1, of one piece construction, an preferably of rubbe'r.

. In the form of tlfe invention shown in Fig. 3, the flange 10 and the body 11 approach each other closely in relativethic nesses, the body 11, however, being thicker than the flange 10, so that the comparative rigidity of the body may be retained. The

neck 12 of the stopper is, as before, in-v sertible into an opening in a receptacle 14:, the receptacle in Fig. 3, being shown in the form of a shaker from which powder of any sort may be dispensed. The stopper shown in Fig. 3, like the stoppers shown Patented Jan. 9,1912.

in Figs. 1 and 2, is referably a one piece,

rubber structure, alt ough any other material possessing the desired resiliency, may be employed.

The foregoing descriptions set forth divers forms which a stopper of this type may take. Preferably however, the device is constructed as shown in Figs. 4, 5 and served until this place, in order that the de-' the description of these figures being re- 45 v will flatten out the top of the receptacle, thereby sealing the re ceptacle effectively.

in close relation to the claims. I In the form of' the invention shown in Fig.v 4, the body The body 15 and the reduced neck of the stop i means of a rivet form 0 lineation, that the is not confined to this 15 is in the form of a flat, rigid disk, the flange 16 being a cup shaped disk; fashioned from resilient material, and having its smaller end disposed toward the body 15.

the flange 16 may be conof a rivet 17 or the like, the structure constituting r, which is inserted into the opening in t e receptacle. In the form of the invention shown in Fig. 5, the. body 19 is frusto-conical, and may be fashioned from rubber. Secured to the lower. end vof the frusto-conical body 19, by or the like, is a cup shaped flange 21, the reduced neck'of the stopperbeing shown at 22. Although the showin nected by means the portion 18 of stopper which is shown in Fig. 1, it is' to be understood without-specific deflanges of the stoppers in all of the other figures of-the drawings, may be disposed. in the tubular form shown in Fig. 5-, the insertion of the sto per into the receptacle, and the I removal stop er therefrom, obviously being facilitated by the fact that the flanges in all forms of the invention may be disposed in tubular shape, as shown at. 5.

The device is intended primarily for the purpose of retaining powders in shakers and other receptacles. The device, however, use", as Fig. 1 will show. The application of the invention shown in Fig. 1 makes it clear. that a'liquid,

'maintaining a pressure within the receptacle, may be restrained byJthe stopper of my invention. When a receptacle such as that denoted by the numeral 4 in Fig. 1 is made to serveas a container for a pressure exerting fluid, such, for instance, as beer or carbonated water, it will beobvious that the pressureexerted within the receptacle, flange 20, against the the stopper be of Fig. 6 applies peculiarly to that of the It is to be noted that no portion ofthe stopper is thrust forcibly into the opening of the receptacle, in contact with the receptacle, the reduced in all instances, approximating the'diameter of the opening in the receptacle, the flange, as denoted by the numeral 5, being adapted to be so disposed, that it may be inserted into the opening in the receptacle, without coming into forcible contact with the recept-acle. portionof the stopper is likely to be sheared away, during the insertion of the stopper into the opening in the receptacle, nor will materially reduced in diameter, through opening, as is the case with a common cork stopper.

When the device takes the form shown in Fig. 5, the same may be employed in the unanner-above described, or the frusto-coni- 70 cal body 19 may be thrust into an opening neck of the stopper,

Owing to this construction, no i frequent insertions into an in a receptacle, after the manner of an ordinary plug stopper.

Having thus described the invention what i is claimed is:

1. A device of the class described comprising a body; and a resilient, inverted, open bottomed, cup-shaped disk having its smaller end disposed toward the body and secured thereto.

'2. A device of the class described comprising a body; and a. resilient, inverted,

open bottomed, cup-shaped disk having its smaller end disposed toward the body and secured thereto; the body being frusto-conical, whereby the body may be inserted into the neck of a receptacle, to serve as a plug therefor; or, neck of th'e'receptacle may tween the disk and the body.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses. OLOF ALBERT CARLSSON. Witnesses:
